Step 1 :The question is asking to predict the grade of a student who spent 14 hours on their homework using the given regression line equation. The regression line equation is a linear equation in the form of \(y = mx + c\), where \(m\) is the slope of the line, \(x\) is the independent variable (in this case, hours spent on homework), and \(c\) is the y-intercept.
Step 2 :Given that the slope \(m = 1.061\), the intercept \(c = 46.027\), and the student spent 14 hours on their homework, we substitute these values into the equation.
Step 3 :The predicted grade is then calculated as \(46.027 + 1.061 \times 14\).
Step 4 :Rounding this to the nearest whole number, we get the predicted grade as 61.
Step 5 :So, the predicted grade for a student who spent 14 hours on their homework is \(\boxed{61}\).
